Can you get past level 4?

Hello! I’ve been playing our game over and over to try and get past level 4. I’ve gotten super close. My main two strategy’s are large mask minions and healing towers, or dart towers and poison with wisps as backup. Let me know if anyone else is able to get past level 4 and let me know how you do it!
